我试图让这些类保持 RAII 标准(正如我所得到的那样......我是一个业余程序员(,但编译器/调试器抱怨缺少构造函数(带空括号(,所以我添加了它们 + set_value(( 函数。

在一个简单的矩形上详细说明这么多的目的是从我试图处理的前景问题中消除集成GUI类型(自上而下的类型,如按钮和文本字段(的云性:openGL 2D和3d图形生活在左下角的坐标词干中。

主测试:

node_handler nh;
glm::dvec2 minor=glm::dvec2(0.0d, 0.0d);
double width=800.0d;
double height=600.0d;
nh.set_root(minor,width,height);
nh.split_current( 1.0d/10.0d , true );
//see nh.split_current() where SIGSEGV happens
